Aggression among combat veterans: Relationships with combat exposure and symptoms of posttraumatic stress disorder, dysphoria, and anxiety

JOURNAL OF TRAUMATIC STRESS, Issue 2 2007
Casey T. Taft
Prior research has revealed heightened aggressive behavior among veterans with PTSD. This study tested a model examining the interrelationships among combat exposure, posttraumatic stress disorder (PTSD) symptoms, dysphoric symptoms, and anxiety symptoms in predicting aggressive behavior in a sample of 265 male combat veterans seeking diagnostic assessment of PTSD. Combat exposure was indirectly associated with aggression primarily through its relationship with PTSD symptoms. Symptoms of PTSD were directly related to aggression, and indirectly related to aggression through dysphoric symptoms. Results highlight the role of PTSD symptoms and dysphoric symptoms with respect to aggressive behavior among this population, and suggest the relevance of aggression theory to the study of combat veterans.

Combat experience and the acquired capability for suicide,

JOURNAL OF CLINICAL PSYCHOLOGY, Issue 10 2010
Craig J. Bryan
Abstract Rising suicide rates are an increasing concern among military personnel. The interpersonal-psychological theory of suicide proposes that three necessary factors are needed to die by suicide: feelings that one does not belong with other people, feelings that one is a burden on others or society, and an acquired capability to overcome the fear and pain associated with suicide. The current study tests the theory's proposal that acquired capability may be particularly influenced by military experience, because combat exposure may cause habituation to fear of painful experiences such as suicide. Utilizing clinical and nonclinical samples of military personnel deployed to Iraq, results of the current study indicate that a greater range of combat experiences predicts acquired capability above and beyond depression and post-traumatic stress disorder symptoms, previous suicidality, and other common risk factors for suicide. Combat experiences did not, however, predict perceived burdensomeness or thwarted belongingness. The authors discuss how combat experiences might serve as a mechanism for elevating suicide risk and implications for clinical interventions and suicide prevention efforts. © 2010 Wiley Periodicals, Inc.

Factors associated with antisocial behavior in combat veterans,

AGGRESSIVE BEHAVIOR, Issue 5 2010
Stephanie Booth-Kewley
Abstract The objective of this study was to identify factors associated with antisocial behavior in 1,543 Marines who deployed to combat zones in support of conflicts in Iraq and Afghanistan during 2002,2007. Five factors were associated with antisocial behavior in multivariate analyses: post-traumatic stress disorder (PTSD) symptoms, deployment-related stressors, combat exposure, younger age, and being divorced. PTSD symptoms had a stronger association with antisocial behavior than any other variable. A unique and important finding of this study was the association between deployment-related stressors and a higher incidence of antisocial behavior. Because deployment-related stressors are potentially modifiable, the military may be able to address them in concrete ways such as by shortening deployments and improving communication with home.

Heterogeneity in the course of posttraumatic stress disorder: Trajectories of symptomatology,

JOURNAL OF TRAUMATIC STRESS, Issue 3 2010
Benjamin D. Dickstein
Unconditional and conditional trajectories of posttraumatic stress disorder (PTSD) symptomatology were examined using a sample of U.S. soldiers deployed on a NATO-led peacekeeping mission to Kosovo. Data were collected at 4 time points, ranging from the weeks leading up to deployment to 9-months postdeployment. Latent class growth analysis revealed 4 unique symptom trajectories: resilience, recovery, delayed, and unrealized anxiety. Variables identified as significant predictors of trajectory class included previous traumatic events, combat exposure, peacekeeping daily hassles, depression, alcohol use, aggressive behavior, stress reactivity, and military rank. Results from this study add to the literature detailing the variability in PTSD course, as well as to the literature pertaining to predictors of PTSD onset and course. [source]


The impact of reported direct and indirect killing on mental health symptoms in Iraq war veterans,

JOURNAL OF TRAUMATIC STRESS, Issue 1 2010
Shira Maguen
This study examined the mental health impact of reported direct and indirect killing among 2,797 U.S. soldiers returning from Operation Iraqi Freedom. Data were collected as part of a postdeployment screening program at a large Army medical facility. Overall, 40% of soldiers reported killing or being responsible for killing during their deployment. Even after controlling for combat exposure, killing was a significant predictor of posttraumatic disorder (PTSD) symptoms, alcohol abuse, anger, and relationship problems. Military personnel returning from modern deployments are at risk of adverse mental health conditions and related psychosocial functioning related to killing in war. Mental health assessment and treatment should address reactions to killing to optimize readjustment following deployment. [source]


The contribution of prior psychological symptoms and combat exposure to post Iraq deployment mental health in the UK military,

JOURNAL OF TRAUMATIC STRESS, Issue 1 2009
Roberto J. Rona
This study assessed the contribution of baseline psychological symptoms, combat exposure, and unit support in the etiology of posttraumatic stress disorder (PTSD), and psychological distress. From 2004,2006, 67% of a random sample of 2,820 participants who had been assessed for psychological symptoms in 2002 were reassessed. Baseline psychological symptoms, combat exposure, and unit support factors were associated with the outcomes and the effect sizes for combat exposure were marked for PTSD symptoms. Adjustment for baseline psychological symptoms did not modify the pattern of association of group cohesion and combat exposures. The authors concluded that combat exposure and group cohesion have an effect on mental health outcomes independent of previous mental health status, which explains why screening prior to deployment is ineffective.

The consistency of combat exposure reporting and course of PTSD in Vietnam War veterans

JOURNAL OF TRAUMATIC STRESS, Issue 1 2007
K. C. Koenen
Self-reports of traumatic events are often used in clinical and epidemiologic studies. Nevertheless, research suggests combat exposure reports may be biased by posttraumatic stress disorder (PTSD) symptom severity, leading to an inflated dose-response relation between combat exposure and PTSD. The authors examined the consistency in combat exposure reports and their relation to PTSD symptoms in Vietnam Veteran American Legionnaires who responded to two mailed surveys (1984, 1998; N = 1,462). Combat exposure reports were highly reliable (test,retest correlation = 0.87). However, changes in exposure reporting were related to changes in PTSD symptoms, specifically reexperiencing symptoms. The effect size of the dose-response relation attributable to changes in reporting was smaller for continuous than categorical measures. Findings are discussed in relation to recent controversies over veterans' combat exposure reports. [source]


Anger and combat-related posttraumatic stress disorder

JOURNAL OF TRAUMATIC STRESS, Issue 2 2002
Raymond W. Novaco
Abstract We examined whether combat-related PTSD was differentially associated with particular dimensions of anger on two multi-index, psychometric instruments and whether the proportion of variation in PTSD scores explained by anger was significantly greater than that by demographic and exposure variables. We also examined the reliability and validity of a subset of Mississippi Scale items as an anger measure. Participants were 143 Vietnam combat veterans. Anger accounted for over 40% of the variance in Mississippi PTSD scores (minus the anger items) above that associated with age, education, and combat exposure. Veterans with structured-interview,diagnosed PTSD were significantly differentiated from those without PTSD on all anger indices. The results point to anger treatment as a high priority for combat-related PTSD. [source]


Examination of predictors of severe violence in combat-exposed Vietnam veterans

JOURNAL OF TRAUMATIC STRESS, Issue 4 2001
Matthew K. Nock
Abstract This study examined several proposed predictors of severe wartime violence in a randomly selected, nationally representative sample of 1,125 Vietnam veterans. Participation in severe acts of violence during wartime was reported by 7.6% of the sample. Disruptive behavior before the age of 15 and increased combat exposure were both significant predictors of severe wartime violence. Childhood contextual factors were indirectly related to severe wartime violence via prewar disruptive behavior. The classification rate of perpetrators of severe violence was comparable to rates from studies of less severe forms of violence. The implications of these results and suggestions for future research in this area are discussed. [source]


An investigation of the impact of posttraumatic stress disorder on physical health

JOURNAL OF TRAUMATIC STRESS, Issue 1 2000
Amy W. Wagner
Abstract In a large sample of Gulf War veterans (N = 2301) we examined the relations between PTSD symptoms assessed immediately upon returning from the Gulf War and self-reported health problems assessed 18,24 months later. PTSD symptomatology was predictive of self-reported health problems over time for both men and women veterans, even after the effects of combat exposure were removed from the analysis. Female veterans reported significantly more health problems than male veterans, however, there was no interactive effect of gender and PTSD on health problems. These findings provide further support for the theory that psychological response to stressors impacts health outcome. [source]
